Webview dasturiga mailto qo'shishga urinish. Ilovani ishga tushirganingizda va pochta aloqasini bosganingizda messengerni ochadi. Nima uchun "http" va "?" mailto tomonidan tan olinmagan va kesilmaydi. Xuddi shu mailto havolasi qurilmalarda an'anaviy brauzerda juda yaxshi ishlaydi. Men olishim kerak bo'lgan yagona maydon - mavzu va tana.
